I finally got a "little" time to get started, in between cleaning poo from 5 cats, making dinner for 2 kids (wife was working), Cleaning up after 2 kids (refusing to help), cleaning the bathroom, driving forth and back to my old mom, just to switch off her broken fire alarm,

.
Anyone that wants to help out porting the 7D2 are warmly welcome, we might actually have some progress in the next
month years, and helping out now is the right time.
My software was 1.1.3 and we're building for 1.1.2 so I needed a downgrade. I'm on linux, and EOS utility 3.0 does not run on linux/wine. I took 1.1.2 and put in on a 32 GB highspeed card, but the camera refused to downgrade (it actually checked the version within the FIR update file) and told me that I has the newest version!. I then renamed the file - pretending it was version 1.1.4, but the camera still refused. Then I took a old slow 8GB card and put the 1.1.2 on it, rename it to look like 1.1.4 and now it wanted to start the update procedure, but it failed right away after pressing ok (some odd message). The solution was to resort to the "dual card - switch card when pressing ok" trick. The final solution was:
My downgrade to 1.1.2

1. Charge your battery to full capacity.
2. Get two CF card, one 8GB and one 32GB.
3. Put Canon firmware "FIR" file for 1.1.2 on both card and change the last digic "2" to "4" in both filenames.
4. Put the 8GB into the camera and initiate the upgrade procedure - but dont press "OK"
5. At the very same time you press "OK" open the card door.
6. Switch the CF cards to the 32GB and close the card door.
7. Wait a minute until the camera allows you to upgrade.
8. Verify that firmware version is 1.1.2
Btw. If your camera break, you get to keep both pieces
Upgrade to 1.1.2:
- Follow canons instructions .. - Follow canons instructions ..
ROM dumper:
- Available at the portable rom dumper page, remember to use a SD card (CF does not work)- Worked fine, screen was red =>
